Fusion sample preparation, also known as sample fusion, is a technique used in analytical chemistry and materials science to prepare solid samples for analysis by various analytical instruments, such as X-ray fluorescence (XRF) spectrometers, inductively coupled plasma optical emission spectrometers (ICP-OES), and inductively coupled plasma mass spectrometers (ICP-MS). The process involves fusing a solid sample, typically a powdered or finely ground material, with a fluxing agent at high temperatures to create a homogeneous glass bead or disk. This glassy sample is then suitable for analysis, allowing for the determination of elemental composition.
Application of Fusion Sample Preparation
Fusion sample preparation is primarily used for preparing solid samples, especially those with complex matrices, for analysis by techniques like X-ray fluorescence (XRF) and inductively coupled plasma-optical emission spectrometry (ICP-OES). These techniques are used to determine the elemental composition of a sample. Fusion is particularly useful when dealing with materials that are difficult to dissolve or that require high-temperature treatment to break down their matrix. Fusion sample preparation is a crucial step in various scientific and industrial applications, particularly in the fields of analytical chemistry, materials science, and nuclear physics. The goal of fusion sample preparation is to create homogeneous and representative samples for analysis, often by melting or fusing solid samples into a glass bead or disk.
Some common applications include:
